In Germany May 11, 1934 6 Claims.

This invention relates to cigar making machines, and is an improvement over apparatus of a character wherein the guide surfaces disposed at the ends of the two controlled levers first take the end of the wrapper (the flag) between themselves and then, with the aid of a support which is capable of being turned about an axis of rotation situated transversely to the longitudinal direction of the filler, move in the longitudinal direction of the filler toward the pointed end of the filler, in which procedure they at the same time follow the profile of the tip. As soon as they have passed beyond the wrapper incision, the inner guide surface goes back, so that only the outer guide surface effects the guidance of the remaining portion of the wrapper while it is being placed around the mouth end of the filler.

This arrangement proves satisfactory in every case where the wrapper is comparatively thick, but does not afford adequate guidance when very delicate wrappers are involved. In the latter case the outer guide surface is unable to prevent the semi-circularly curved flag, as is evident from an examination of Fig. l of the drawings, from rolling up conically at 1 beyond the end of the filler, whereas it really should be applied smoothly to the fi1ler-end E.

In order, therefore, to prevent the rolling up of the end of the flag or wrapper, the support for the control levers carrying the guide surface is pivoted so as to be capable of being turned by means of a movement about an axis which is arranged perpendicularly to the axis of rotation of the support, and which passes through the longitudinal medial line of the cigar filler, and it is further controlled in such a way that after the removal of the inner control surface a turning takes place of the outer control surface toward the tip of the filler.

The flag or wrapper is cut or incised by means of shears, and in order to prevent interference of the shears with the movement of the guide surface, the shears are so mounted as to be movable away from the filler tip, being movable in 45 the direction of the filler tip only at the time of the incision.

The shear axis is arranged on a swinging lever which, after the blades of the shears have come together for the purpose of making the flag inci- 50 sion, is swung downward, so that the blades of the shears are removed from the region of the tip of the cigar filler.

Inasmuch as the support of the guide surfaces must, in accordance with the invention, also execute a swinging movement about an axis disposed at right angles to it, the control means for the axis of the support cannot be connected rigidly with this axis. There is, therefore, expediently adjoined to the axis of the support a control rail, curved in arc shape, which is carried by a com trol rod system and which coacts with a lever which is attached to the axis of the support, in

that a torsion spring placed upon the axis imparts to the latter a tension to maintain the lever against the control rail.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

Referring now to the drawings, and first to Figure 2, the character Z designates a filler about which a wrapper D is adapted to be wound, and the filler Z is disposed between filler rollers W.

A pair of opposed rock arms 3 and 4 are provided with wrapper guide surfaces l and 2, respectively, and these guide surfaces extend obliquely to the horizontal plane, but in the main in the longitudinal direction of the filler Z. When the guide surfaces I and 2 are disposed in their operating position they are disposed as shown in Fig. 2 above the axis of the filler Z. The guide surfaces I and 2 are here shown as flat, but it will be understood that these surfaces may also be of a different configuration.

The arms 3 and 4 are swingably mounted on supports 5 and 6, respectively, and the arm 3 is provided with a pin 1 on which an end of a spring 8 is attached. The other end of the spring 8 is attached to apin 9 carried by a lug or extension I0 secured to the support 5. The spring 8 constantly urges the arm 3 downwardly for contact with a control cam II which is secured on the frame of the machine at one side of the filler rollers W adjacent the tip of the filler. This control curve or cam fixes the shape of the tip of the filler, or in other words, the cam I I by its shape governs the shape of the tip of the filler.

The arm 4 is connected with a pin |2 which is engaged by a spring I3 which is attached as at I4 to an extension I5 of the support 6. The spring l3 constantly urges the arm 4 upward, and the upward swinging of the arm 4 is limited by the guide I6 which is attached to the frame of the machine adjacent the filler rollers W. The guide I6 holds the surface 2 in contact with the surface for the major portion of the filler or until the stroking on position of the arm 3 has been reached.

The arm 5 is mounted on a bearing I8 which is swingable on a bolt or shaft I1, and the normal position of the support is an upright position as shown in Fig. 2. This normal or upright position is maintained by means of a spring I9 which engages the pin 9 on the extension I9 and also engages a pin 29 on the bearing I8. By reason of this mounting the support 5, together with the arm 3 and the guide surface i, can be swung into a new position in a plane which is transverse to the longitudinal direction of the filler.

The support 5 of the arm 4 is rotatably mounted on a bolt 2! carried by a bearing 22, and a spring 23 has one end secured to the pin I4 while the other end is secured to a pin 24 carried by the bearing 22. This spring 23 acts to constantly urge the support 6 toward the cam member 15. This support 6 is also mounted for swinging movement perpendicularly to the longitudinal direction of the filler.

The two bearing members I8 and 22 are fixedly mounted on a shaft 25 disposed transversely to the longitudinal axis of the filler Z, and the shaft 25 is supported in a block 59. The rock shaft 25 is swung in a horizontal direction by means of a vertical shaft 53 which is attached at one end to the block 58 and is journalled in bearings 5| and 52 carried by the frame of the machine. The lower end of the shaft 53has a gear 54 mounted thereon, and a swinging lever 55 is provided with a toothed segment 56 meshing with the gear 54. The lever 55 is swingably mounted on a pin 51 attached to the machine frame, and swinging movement of the lever 55 is effected by means of a roller 58 which is carried by the lever 55 intermediate the ends thereof and which engages a cam surface 99 provided on a drum 59.

A torsion spring 6| is mounted on the shaft 25, one end of the spring 8| being attached to the block 59, and the other end to a collar 52 fixed to the shaft 25. A laterally projecting arm 63 has a roller 94 mounted thereon which is maintained in contact with a guide member 65 by means of the spring 6 I. The guide member 65 is carried by an end of a lever 56 mounted on a pivot 5! carried by the machine frame. The opposite end of the lever 65 has one end of a link 68 secured thereto, and the link 58 has its opposite end secured to a bell crank lever 99 pivoted as at IE to the machine frame. The bell crank lever 69 has a roller II mounted thereon, and this roller I| engages a lifting cam 72, also provided on the drum 59. The roller II is maintained in contact with the cam 52 by means of a spring I4, one end of which is secured to the link 69 and the other end of which is secured to a part of the machine frame.

The controlling of the supports 5 and 6 is effected by means of the three-armed lever 35, 31 and 38 which is pivoted as at 36 to the machine frame. The arm 35 projects downward from the pivot 36 and a roller 34 is mounted on the lower end thereof which roller engages a lifting cam 3| on the drum 59. The arm38 projects upwardly of the pivot 36 and is provided witha cam member I5 against which the support 6 engages, being held in engagement with the cam member I5 by the spring 23. The arm 31 engages beneath an extension I6 of a lever I8 which is mounted on a pivot 11. The extension or arm 31 engages beneath the extension or arm 16 so that upward rocking movement of the arm 31 will effect an upward movement to the extension or arm I6, so that the two cam members I5 and I9 will move toward or away from each other under the rocking movement of the lever 35, and in this manner the arm supports 5 and 6 will be rocked upon their pivots I! and 2|, respectively. This lever I8 has a cam I9- on the upper end thereof, and the support 5 is maintained in contact with the cam I9 by means of the spring l9.

In order to effect a cutting of the wrapper or flag at the proper moment, I have provided a pair of shear blades 86 and 8|, which are swingably attached to the lever arm 83, being disposed on a pivot 82. The lever 83 is swingably mounted on a pivot 84 secured to the machine frame. A lever 86 is mounted on a pivot 85 carried by the machine frame, and a spring 81 is secured at one,

end to the outer end of the lever 86 and at the other end to the frame of the machine, to constantly urge the lever 86 downwardly at the outer end thereof. The lever 86 is provided with a nose 88 engaging a cam 89 fixed on the drive shaft A. The opposite or inner end of the lever 86 is provided with a toothed segment 99 which is in engagement with a toothed segment 9| carried by the inner end of the lever 83.

A lever 92 is rockably mounted on the pivot 84, as shown in Fig. 5, and this lever 92 is provided with a toothed segment 93 which meshes with a toothed segment 94 carried by a rock lever 9-5 mounted on the pivot 85. A spring 96 engages the outer end of the lever and maintains the lever 95 in contact with a cam 91. An upper roller 98 and a lower roller 99 are mounted on the lever 92, and the upper roller 98 engages an edge of the blade 8|. The blade 89 is provided with an extension or arm IDI which engages the lower roller 99. The two blades 88 and 8| are constantly urged apart by a spring ID!) as shown in Fig. 4.

In the operation of the apparatus, after the insertion of the cigar filler Z in the filler rollers, the wrapper D which is brought up by the carrier T, is laid around the filler, beginning from the end to be lighted. At this point the guide surfaces and 2 are in the position shown in Fig. 6.

When the wrapper D, in being laid around the filler, arrives in the region of the tip of the filler, the guide surfaces and 2 will close under the swinging of the shaft 25 which is effected through the cam 3| which rocks the arm. 35. The swinging of the shaft 25 will effect swinging of the supports 5 and 6 which contact with the cam members 79 and 75 respectively. As the arms 3 and 4 are rocked upwardly, the guide surface 2 will move toward the surface I, the surface I being moved outwardly by the cam 19 so that the surface 2 may readily engage therebeneath. The tension of the springs 8 and I3 on the arms 3 and 4 respectively is such that the wrapper may freely move between these two guide surfaces. The guide surfaces and 2 will close when the roller 34 carried by the arm 35 engages the depression of the cam 3| so that the lower end of the lever 35 will be rocked to the right, as viewed in Fig. 2 and the support holding members 15 and 19 will be swung toward each other. As the members 15 and 19 move toward each other the springs 19 and 23 will draw the supports and 6, respectively, inwardly maintaining contact with the members I5 and 19.

When the guide surfaces I and 2 have closed, the supports 5 and 6, actuated by the mechanism 65-12 begin their swinging movement in the longitudinal direction of the filler. In this movement the guiding cams II and I6 effect a movement of the arms 3 and 4 in conformity with the configuration of the tip of the filler. It will, therefore, be seen that the guide surfaces l and 2 not only move in the longitudinal direction of the filler tip. The end of the wrapper is thus guided by means of the guide surfaces I and 2 in conformity with the progressive application and the profile of the filler tip.

As soon as the end of the wrapper has entered between the shear blades 80 and 8|, the lifting cam 91 has moved to the position shown in Fig. 4. A further turning of the drive shaft A will cause the nose of the lever 95 to slip off from the cam 97, as shown by the dotted line position in Fig. 4 for the lever 86 which is shaped similar to the lever 95. The cam 91 is turned in the direction shown by the arrow in Fig. 4, and when the lever 95 reaches the end of the cam 91 it drops off sharply, the shear blades 80 and BI being thus brought together for making the corresponding incision. As soon as the incision has been made, the lever 86 will be freed by its lifting cam 89 and this lever will assume the position shown by the dotted lines in Fig. 4. Downward movement of the lever 86 will effect a lowering of the lever 83 to the dotted line position, thus swinging the shear blades 80 and 8| to inoperative position.

After the end of the wrapper has been cut off, the cam 69 is effective, and the shaft 53 is swung in the direction of the arrow shown in Fig. 3. During the swinging of the shaft 53 the support 6 is swung outward by the cam 15 in such a manner that the guide surface 2 is drawn back out of the region of the end of the wrapper and that only the guide surface I is maintained in contact with the wrapper to effect a stroking-on action on the end of the wrapper.

As a result of the swinging of the supports 5 and 6 into the position shown in Fig. '7, the guide surface I, while it is being moved a little farther downward, that is, is brought closer to the medial axis of the filler from the control cam II, exeouted a stroking-on movement similar to the movement a cigar maker executed manually with his thumb in the corresponding work. In this manner a neat and entirely smooth application of the wrapper flag to the cigar tip is secured. The tip of the cigar is supported by means of a suitably shaped support I02, which also acts to smooth the wrapper. This support I02 is adjustably attached to the machine by means of a screw I03.
